o.-- IMPROVEMENT IN SHING-LE-'MACHINES The Sched'ule referred to in these Letters Patent and making part of the same.

To all -zvhom 'it may concern:

Be it known that I, O. T. WILLIAMS, of Smithland, in thecounty of Livingston and State of Kentucky, have invented a new and improved Shingle- Machine; and I do hereby declare that the following isi' a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the saine, reference being had to the accompau ying drawing forming part of this specilication.

This invention relates to improvements in shinglemachines designed to provide 'a .simple and eticient machine capable of riving the shingles, shaving them on both sides, and reducing them to the required taper simultaneously.

It consists in the arrangement, upon a verticallyreciprocating gate, of a riving and two sha-ving and tapering-knives, ope-rating ill conjunction with a holding-table and shingle-blank support, all as hereinafter more fully specified.

Figure l represents a sectional elevation Of my, improved' machine, and

Figure 2 represents a plan view thereof.

Similar letters of reference indicate corresponding arts.

p A represents a holding-table for the bolt, which isplaced thereon upon one end, to be fed up to the knives by the operator.

This table is arranged in front of two posts, B, which serve for the supporting of a gate Or pair ofA slides, for supporting and operating'the knives, reciprocating motion being imparted thereto by connecting- .rods .from a crank-shaft, D, at the bottom.

These slides G' support a living-knife, E, working in straight lines, and cutting past the edge F of the holding-table. They also each support two auxiliary knife-holders, G G', connected thereto at H, and rising up to the top of the said slides, where theyA have ledges, I, projecting toward the vertical plaueof the driving-shaft, and supporting the shaving and tapering-knives K face to face.

These ends of the said knife-supports are capable of moving to.or from each other and the ends of the knives K, which they support, project behind guides, L, fixed to the posts B, and so arranged as to draw the said knives toward eachother as they descend. When they rise, they are moved in theop'posite direction by the said guides.

-M represents a gauge, connected to the slides, and

low the living-knife, and take the blanks between them, drawing closer together as they mov-e toward the point of the shingle, which is supported, after being severed from the block or bolt, on the rest N.

The knives K pass suiciently below the restN, to allow the nished shingle to fall over them to the rear for discharging; and to facilitate discharging them in that direction, a defleeting-spring, O, is placed above the front knife K, and adapted to discharge the shavings also.

By removing the knives K, my improved machine is adapted for riving shingles, stares, or other articles having parallel sides, and I, therefore, propose to so connect the said knives as to permit them to be readily detached.

Having thus described my invention, .l claim as new and desire to secure by Letters -Patent- The arrangement, herein described, of the supporting-table, living-cutterE and two shaving and taperingknives,and rest N, when constructed and. operating in the manner and for the purpose set forth.
